Try replacing your current 2 stroke oil with 100 percent synthetic 2 stroke oil. Available at any motorsports dealer. Worked for my Razz. Has not smoked since.
There are several reasons why a Yamaha Razz may quit running. These include issues with the engine, its age, issues with spark plugs, lack of gravity, lack of oil, lack of gas, etc.
If gas is leaking from a Yamaha Razz muffler, then the float may not be set correctly. This means that it is not shutting the intake off.

For the Yamaha Razz, it's recommended to use a high-quality gear oil, typically a 75W-90 or 80W-90, depending on the climate and riding conditions. Always refer to the owner's manual for specific oil specifications and capacities to ensure optimal performance. It's important to use oils that meet the manufacturer's standards for best results.
To remove the oil tank from a Yamaha Razz, first ensure the engine is cool and disconnect the battery. Then, locate the oil lines connected to the tank and carefully detach them, using a container to catch any spilled oil. Next, unscrew any mounting bolts securing the oil tank in place, and finally, lift the tank out of its compartment. Make sure to follow proper safety precautions and dispose of any oil properly.

It holds 700 cc of 10w-30 motorcycle oil ( or .7 litres ). I know this because I just got done replacing my clutch and drive chain.
